MEAN WELL NPF-120D-12 120W Single Output LED Driver Owner's Manual

NPF-120D series is a 120W AC/DC LED driver featuring the constant current mode output. NPF-120D operates from 90~305VAC and offers models with different rated voltage ranging between 12V and 54V. Thanks to the high efficiency up to 90%, with the fanless design, the entire series is able to operate for -40 C~+90 C case temperature under free air convection. The entire series is rated with IP67 ingress protection level and is suitable to work for a variety of applications at dry, damp or wet locations. NPF-120D is equipped with the 3 in 1 dimming function so as to provide the design flexibility for LED lighting system.

DRIVING METHODS OF LED MODULE

※ This series works in constant current mode to directly drive the LEDs.

DIMMING OPERATION

※ 3 in 1 dimming function

‧Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-: 0 ~ 10VDC, or 10V PWM signal or resistance.
‧Direct connecting to LEDs is suggested. It is not suitable to be used with additional drivers.
‧Dimming source current from power supply: 100μA (typ.)

◎ Applying additive 0 ~ 10VDC

Note : 1. Min. dimming level is about 6% and the output current is not defined when 0%< Iout<6%.
2. The output current could drop down to 0% when dimming input is about 0kΩ or 0Vdc, or 10V PWM signal with 0% duty cycle.

※ Auxiliary DC operation (for BE-type)
‧ AUX+, with mark ***, is added for BE-Type, used as the Auxiliary DC output with respect to DIM-.
